Brief introduction of waterborne coatings

Water-dilutable coating refers to the coating prepared by dissolving solvent-based resin in organic solvent after emulsion is used as film-former, and then dispersing the resin in water by strong mechanical stirring with the aid of emulsifier to form emulsion, which is called post-emulsion emulsion. The prepared coating can be diluted with water during construction. Water-dispersible coatings mainly refer to coatings prepared with synthetic resin emulsion as film-forming substance.

Emulsion refers to the dispersed emulsion composed of small particles dispersed in water, which is polymerized by unsaturated vinyl monomer in the presence of emulsifier at a certain temperature during mechanical stirring. Coatings made by adding a little emulsion to water-soluble resin cannot be called latex coatings. Strictly speaking, water-diluted coatings can't be called latex paints, but they are also classified as latex paints customarily.

As the name implies, water-based paint is a kind of paint with water as the medium. For example, all our interior and exterior wall coatings, metallic paints and automobile paints have corresponding water-based coating products. It can be seen that waterborne coatings have been widely used in many industries. What we are generally concerned about is waterborne wood paint, which is the product with the highest technical difficulty and scientific and technological content in wood paint. With the enhancement of people's awareness of environmental protection, water-based wood paint is more and more popular in the market because of its advantages of non-toxicity, tasteless, less volatile matter, high safety, no yellowing and large coating area. Many enterprises also set off a big wave of environmental protection at this time, each took a fancy to the future development trend of environmental protection and improved their products. But so far, only a few enterprises in the national waterborne coatings can achieve complete environmental protection and fully meet CCEL standards.
